When it is desirous of setting the hands 63 and 68 in operation,electrical power will be transmitted to the synchronous motor M toenergize the same. Rotary motion from the motor M will be ltransmittedthrough the drive shaft I8, the intermeshing reduction-gears within thespeedreduction gear-unit I1, the rotary shaft I9, pinion and disc-gear24, which disc-gear 24 will freely rotate on the shaft 23. The/ operatorwill now complete circuit through the onductors 32 and 35 by closing thecutout-switc 33. As soon as circuit is thus established, current will betransmitted through the solenoid 29 and the same will be energized. Uponenergization of the solenoid 29, the armature 30 will be moved upwardlythereby and the outer end of the rocker-lever 36 will be raisedupwardly. Through the medium of the pins 28 and the tongues 31 of therockerlever 36, the clutch-disc 26 will be forced to bear against thedisc-gear 24 and will cause intermediate frictional engagement of thesame between the respective clutch-discs and 26. As soon as engagementis thus established, the rotary motion of the disc-gear 24 will betransmitted throughvthe clutch-discs 25 and 26 to the axle 23 and rotarymotion will be transmitted through the bevel-pinion 38, bevel-gear 41,vertical shaft 45, bevel-gear 48, bevel-pinions 54, rotatablestub-shafts 52, cylindrical connecting-members 68, rotatable spindles 51and hub-discs 61 to the 4members 56, spindles secondary hands 68. As thevertical shaft 46 rotates, rotary motion will be transmitted through thegear-wheel 1I, gear-wheel 91, vertical shaft 96, bevel-gear 98,bevel-gear |02, shaft |00, worm-pinion |0I, worm-gear |04, coil-spring|06, drum |05, vertical shaft 46, bevel-gear 49,'bevelpinions 53, hollowstub-shafts 5|, cylindrical connecting-members 56, cylindrical spindles55 and hub-discs 62 to the primary hands 63. The intermeshingrelationship of the worm-pinion IOI and the worm-gear |04 have apredetermined speed ratio.

If desirous of setting the hands 63 and 68 at a predetermined locationaround the dials I4, the operator will complete circuit between theconductors 82 and 35, also between 32 and 35 by closing thecutout-switch 84 and opening the cutoutswitch 33. As soon as circuit isthus established, current will be transmitted through the solenoids 80and 29. The energizing of the solenoid 29 will set the hands 63 and 68in time operation (as described inthe preceding paragraph). Thesimultaneous energizing of the solenoid 80 will simultaneously put mytime indicating device in reset operation and the armature 8| will bemoved upwardly carrying with it the rod 81. As the rod 81 movesvertically, the expansion spring 9| will be compressed between thewasher 89 and the outer end of the rocker-lever 16. As the spring- 9| iscompressed. the same will tend to move the outer end of the rocker-lever16 upwardly and through the mediums of the rocker-lever 16, pins 19 andsemi-annular collar 18, the portion 13 of the jaw clutch will be moveddownwardly against the portion 31. of the jaw clutch. As the verticalshaft 45 continues to revolve, the portion 12 will be revolved and whenthe interlocking shoulders of the portion 12 revolve to an interlockingposition relative to the interlocking shoulders of the portion 13, theexpansion spring 9| will rock the rocker-lever 16 to cause the portion13 to move into interlocking engagement with the portion 12. As lockingtakes place between the portions 13 and 12, rotary motion will betransmitted from the portion 12 .through the portion 13 to thecylindrical shaft 46 and through the mediums of the bevel-gear 49,bevel-pinions 53, cylindrical stub-shafts 5|, interconnecting- 55 andhub-discs 62 to the primary hands 63. In this manner, the primary andsecondary hands will be revolved around the respective dials I4 at thesame rate of speed. The relationship of the portion 13 to the hollowvertical shaft 46 is such that upon interlocking engagement between theportions 13 and 12, the primary and secondary hands will be in direct.overlapping alignment with each other. As rotation is transmittedthrough the portions 13 and 12 to the cylindrical shaft 46, the drum |05will be rotated in a contra direction to the windings of the coil spring|06 and the tensional engagement of the coil spring |06 on the drum |05will be neutralized.

Thus the coil spring |06 acts as a clutch on the drum |05 when the wormgear |04 is rotated but will be non-operative when the worm gear |04 isstationary.

When the hands 63 and 68 have been rotated to the desired positionrelative to the indicia on the dials |4, the operator will open thecutoutswitch 84. Consequently circuit to the solenoids 80 and 29 will bebroken and the armature 8| will drop, causing the rocker-lever 16 torock and release the portion 13 from engagement with the portion 12 ofthe jaw clutch. When it is again devhands as hereinbefore described.

The indicia visible through the openings |65 and |69 indicatethe number of goals or points scored by the respective opposing teams.In Fig. l, I have shown the word "visitors and the words home teamopposite the respective vision openings |65 and I 69.

If the visiting team scores a goal, the operator will close thecutout-switch |34 and electrical current will be transmitted to thesolenoid |3|.

As the solenoid |3| is energized, the armature clutch-disc |21 and theclutch-disc |08. As engagement takes place between the clutch-discs |21and |08, rotary motion will be transmitted from the clutch-disc |08through the medium o1' the clutch-disc 21, rotary shaft |26, bevel-gear|43, bevel gear |44, rotary shaft |40, bevel-gear |46, bevel-gear |59,vertical shaft |58 and drum |60.

A flexible cable may be secured adjacent theroof of the auditorium, suspended downwardly through the vertical shaft|88 and platform |18 and secured to a suitable drum within the casingI2, which drum may be provided with a. solenoid-operated clutchmechanism rotated from the synchronous motor M, which provides motivepower for the various mechanism used in my time indicating device.

In various sporting contests, where the time periods vary, differentstyles of dials may be used and the transmission mechanism of my timeindicating device adapted to operate the hands in conjunction with suchdials. For example, in hockey games, it may be desirous to record therespective 20-minute periods by a complete revolution of the primaryhand 63 and one revolution of the secondary hand 68 to indicate oneminute passage of time. This could readily be accomplished by alteringthe gear ratio of the transmission mechanism.

Referring to the modified form of my invention as disclosed in Figs. 12,13 and 14, I2 is the casing which is provided with dials I4', which havein combination herewith the primary and secondary hands 63 and 68'respectively.

Thenumerals 1 to 9 respectively, of the indicia 2|4 are laterally disposedin consecutive relationship while the tens portion of the indicia forml0 to 20 respectively are disposed above their respective units portionof their indicia. so that in this manner it is possible to have amaximum number of numerical indicia imprinted on the endless belts 2|3.This method is also preferably used in printing the indicia 2I8 on theendless belts 289. 2|6 are endless drive chains which are trained oversprockets carried by the respective adjacent drums 2| 2 thus linking thesame together in pairs. 2|1 are endless drive chains which extendbetween the diagonally opposite pairs of drums 2|2 and trained aroundsprockets carried by one of the drums of said pairs. In this manner theunits formed by the sets of triangularly disposed drums 2|| and 2|2respectively at diagonally opposite corners of the casing |2a are inseries asa unit and upon rotation being imparted to one of said setsrotation will also be imparted to its adjacent set and the setsdiagonally opposite thereto. 2|8 are reversible motors which, throughthe medium of the shafts 2|9, gear reduction units 220 and endless chainbelts 22|, which are each trained around a sprocket carried by theadjacent rotatable drum 2|2 and around a sprocket 222 forming a part ofeach of the gear reduction units 220, are adapted to transmit rotatablemovement to the respective units-composed of the sets of drums 2| |-2|2as just hereinbefore mentioned. The construction composed of the members20| to 222 inclusive is duplicated at the bottom of the modied form ofmy time indicating device with the indicia 2 I0 and 2|4 visible throughthe openings |69' and 2|5 respectively.

Supported adjacent each of the vision openings 2|5 respectively is apenalty recording dial 223. The function of the four openings 2|5 is toshow the number of players beingV penalized, each opening being providedfor use in conjunction with its adjacent penalty timer 223.

The other arm of each of thebell-cranks 235 has connected thereto the armature 231 of a solenoid 238so that upon energization of one of the solenoids 238 the armature 231will cause its respective bell-crank 235 to move its respective clutchdisc 233 into contact with its respective clutch-disc 230 to transmitmovement from its respective spindle 55a, sprocket 232b, chain belt232a, sprocket 234, clutch discs 233 and 230 and its shaft 228 to itsrespectivD minute-hand 229.

The solenoid 238 of the adjacent clutch trans- 254, similar to theterminal point 243.

mission mechanism at the respective corners of the casing |2' areconnected by means of electrical conductors 239 and 240 respectivelywhich conductors are illustrated in the schematic view Fig. 17 in theircircuit relationship.

Referring more specically to Fig. 17 inv which is illustrated theelectrical circuits and means for controlling the operation of thepenalty recording elements, 24| is an armature switch adapted to closecircuit between the terminal points 242 and 243 respectively. 244 is anelectromagnet having a conductor 245 as leading from one side thereof tothe fixed end of the armature switch 24| and a conductor 246 leadingfrom its opposite side to the incandescent lamp 226. 241 is a conductorleading from the incandescent lamp 226 to one side of a normally closedswitch 248 which switch is adapted to be opened by the minute-hand 229as the same contacts therewith. 249 is a conductor which leads from anysuitable source of supply and which conductor is connected to theopposite side of the switch 248. 250 is a conductor connecting betweenthe conductor 239 and the terminal point 242. conductor which isprovided with a cutout switch 252. The supply conductor 25| is connectedto the terminal point 243. 253 and 254 are switch housings which haveenclosed therein armature switches similar to the armature switch 24|and electromagnet 244 with similar associate conductors and terminalpoints as just hereinbefore referred to in connection with the armatureswitch 24|. 239 is a junction conductor leading from the conductor 239and which in turn has junction conductors which communicatewith theterminal points in the housing 253 and 254, similar to the terminalpoint 242. 25| is a junction conductor extending from the conductor 25|and which in turn has junction conductors communicating with theterminal points, in the housing 253 and 246 is a conductor extendingfrom the electromagnet in the housing 253 to the incandescent lamp 225.246 is a conductor extending from the electromagnet in the housing 254vto the incandescent lamp 221. 241 is a conductor leading from theincandescent lamp 225 to one sidelof-anormally closed switch 248 whichswitch is/adapted to be opened by the minute-hand 229 as'the samecontacts therewith. 249' is a conductor extending between the switches248 and 248. 241 is a conductor leading from the incandescent lamp 221to one side of a normally closed switch 248 which switch is adapted tobe opened by the minute hand 229 as the same contacts therewith. 249" isa conductor extending between the switches 248 and 248".

If during a sporting contest one of the contestants is penalized for veminutes the'operator of the time recording device will close a switch(hereinafter referred to) to transmit energy to the motor 205, which,through the medium of the shaft 206, gear reduction unit 201, gear 204,and drums 208 and 202 will cause the endless belts 209 to rotate untilthe indicia as at 2|0, indicating the contestants number, is visiblethrough the.

vision opening |65 or |68 accordingas to whether the contestant isplaying for the home team or the visitors. The operator will then pressthe button 24| on the switch 24| to close the same. As the switch 24| isclosed current will iiow through the circuit comprised of the conductor25|, terminal 243, switch 24|, conductor 245, induction coil 244,conductor 246, incandescen. lamp 226, conductor 241, switch 248 andconducis a supply tor 249, thus causing the incandescent lamp 226 tobecome illuminated and the electromagnet 244 to become energized andwhich electromagnet through its magnetic attraction will retain theswitch 24| in closed position relative to the terminal points 243 and242. At the same time electric current will be circulated from theterminal point 243 through the switch 24|, conductor 250, conductor239,.solenoid 238, conductor 240 and conductor 249. As current passesthrough the solenoids 238 the same will become energized and willconsequently operate their respective bell-cranks 235 to move theirrespective clutch discs 233 into contact with their respective clutchdiscs 230 and consequently rotary motion will be imparted as justhereinbefore described to their respective minute-hands 229. At theexpiration of five minutes Vthe minute hands 229 will have registeredand opened their respective switches 248 and consequently broken circuitto their respective incandescent lamps 226, solenoids 238 andelectromagnets 244. As circuit is broken .to the electromagnets, thesame, becoming deenergized will release their respective armatureswitches 24| and current will be permanently broken between the terminalpoints 242 and 243. At the same time, as circuit is broken to thesolenoids 238, the same, becoming deenergized, will release theirrespective bell-cranks 235 and consequently the clutch discs 233 willrelease their respective clutch discs 23|) and as the same are thusreleased the recoil springs 23| will rotate their respective shafts 228to return their respective hands 229 to normal upright inoperativeposition. It will be appreciated that upon closing the switches 24| inthe switch housings 253 and 254. their respective incandescent lamps 225and 221 will bc illuminated and their respective solenoids 238 energizedas hereinbefore described until either of the switches 249 or 248" areopened by the respective minute hands 229. From the foregoing it will beappreciated that indication is given to all officials, contestants andspectators, of the penalized contestants numbers, the length of time ofthe penalties imposed and indication of the passage of time for theduration of such penalties. In this manner accurate indication is givenof the moment the penalized contestant is to leave the play and themoment at which he is entitled to resume the play and during suchpenalty, indication is at all times given as to the part time of suchpenalty served and the remaining time of the penalty to be served beforethe contestant can resume play.

Referring to Fig. l2 it will be noted that each face of my timeindicating device is provided with two penalty dials f-or the home teamand two for the visiting team so that in this manner two contestants oneach respective team may be serving penalties and full particulars areindicated as to the time served and the unexpired time of the penaltiesof each of said contestants. If desired a greater plurality of penaltydials may be provided fory each of Athe respective teams but pref-'erably I use two penalty dials for each team as in modern sports therules and regulations afford for the penalization of a maximum of twocontestants on each team.

Referring to Fig. 19, in which I have illustrated the preferred controlboard for the operator, 255 is the switch which controls the motoradapted to operate the score drums and associate `score indicia beltsfor thev home team. 256 is the switch which controls the motor adaptedto operate the score drums and associate score indicia belts for thevisiting team. 251 and 258 are the switches which control the motorswhich are adapted to operate the respective drums and associate indiciabelts to indicate the penalized players numbers for the home team while259 and 260 are the switches which control the motors which are adaptedto operate the respective drums and indicia belts to indicate thenumbers of the penalized players for the visiting team. 24|" indicatesthe buttons which are adapted to be pressed to operate the armatureswitches 24| in circuit with the respective incandescent lamps 225, 226,and 221 respectively.

Referring to Fig. 18, I disclose the electrical circuit between each ofthe switches 255-288 inclusive and their respective motor. In this viewthe switch S corresponds to any one of the just hereinbefore mentionedswitches 255 'to 260 inclusive, while the motor M represents either ofthe motors 205 or 2 I8. In this circuit the switch S is pivotallyconnected to a.l terminal 36| which has connected thereto a supplyconductor 262. 263 is an arcual rheostat at one side of the switch Swith which the switch S is adapted to contact to complete circuitbetween the conductor 262 and the conductor 264 which leads from therheostat 263 to the motor M. 265 is the return conductor from the motorM. 266 is an arcual rheostat at the other side of the switch S and withwhich the switch S is adapted to contact to complete circuit between theconductor 262 and the conductor 261 which leads from the rheostat 266 tothe motor M. The conductors 265 and 261 are so connected to thereversible motor M that upon throwing the switch S into contact withoneI of the rheostats 263 or 266 the motor will rotate in one directionand upon throwing the switch S vto contact with the other rheostat themotor will rotate in va reverse direction. It will be appreciated thatthe degree of movement of the switch S contacting with either of therheostats 263 or 266 will increase or decrease the speed rotation of themotor M.

Referring to Figs. 12 and 16, 268 is a timing dial the periphery ofwhich is divided into equal parts by means of second indicia points 269.In this modied form of my invention the vertical shaft 45 is extendedupwardly through the motive mechanism casing |6a as at 45. Reciprocallymounted in keyed relationship to the shaft 45 I provide a clutch disc218. 21| is a frame supported above the motive mechanism casing |6a,which frame supports a solenoid 212.-

213 is a forked lever pivotallyr connected at one end to the frame 21|,as at 214, while the forked end thereof straddles a grooved collar 215which is f'lxedly connected to thev clutch disc 218. The armature 212 ofthe solenoid 212 is pivotally connected to the forked lever 213 as at216. 211 is a shaft rotatably supported by the frame 21| in verticalalignment with the shaft 45. Fixedly supported on the upper end of theshaft 211 is a bevel gear 218. Fixedly mounted on the lower end of theshaft 211 is a clutch disc 219: 28|) is a recoil spring fixedlyconnected at its upper end to the frame 21| and at its lower end to theclutch disc 219,. 28| are bearings supported on the frame 21| and whichbearings support the inner ends of the rotatable shafts 282 extendingrespectively through each wall of the casing |2 and through the dials268. 283 are bevel pinions fixedly mounted on the inner ends of each ofthe rotatable shafts zaz and in mesh with the bevel gear 218. Fixeoxymounted on the outer end of each of the rotatable shafts 282 is a secondhand 284.

In certain instances such'as at the end of a contest where 10 seconds ofplay remain before nishing the game, the operator will close a suitableswitch to energize the solenoid 212 which will cause the armature 212'to pull the lever 213 upwardly which in turn will force the revolvingclutch disc 210 into contact with the clutch disc 219 and impartrotation thereto. As the clutch disc 219 rotates it will, in turn,rotate the shaft 211 and through the medium of the bevel gear 218, bevelpinions 283 and rotatable shafts 282 cause the second hands 284 torevolve around the dial 268. The ratio between the bevel pinions 283 andbevel gear 218 is such that rotary motion will be imparted from theshaft 45 to the hands 284 in such a manner that the hands will take 10seconds to revolve cempletely around the dial 268. Thus the oiTicials,contestants and spectators are aware of how many seconds remain beforethe nal gong to announce the end of the game. Upon shutting off circuitto the solenoid, the same, becoming deenergized, will allow the armature21| and lever 212 to drop and consequently frictional engagement will bebroken between the'clutch discs 210 and 219. After frictional engagementis thus broken the recoil spring 280 through its tendency to return tonormal position will rotate the clutch disc 219 in a contra directionand consequently through the medium of the shaft 211, bevel gear 218,bevel pinions 283, and rotatable shafts 282, the'hands 284 will berevolved in a reverse direction around the dial 268 to normalnon-registering position. If desired suitable means (similar to thatdisclosed in Fig. may be provided whereby the hands 284 as they revolvearound the dial 268 will, upon registering with each of the indiciapoints 269, cause a bell or gong to ring. This would be found mostadvantageous in connection with boxing tournaments in instances when onecontestant is down .'or the count. In such instances an omcial wouldimmediately throw the switch to energize the solenoid 232 upon acontestant going down and the intermittent ringing 0f the bell wouldyindicate the expiration of one second intervals. If the contestantshould arise before the full 10-second count were completed the oilicialwould open the switch to deenrgize the solenoid 212 and the recoilspring 280 through the medium of the bevel gears and rotatable shaftsreturn the hands 284 to normal non-registering position.

Referring to Fig. 20, I illustrate a means whereby the dial |4 andassociate hand 68' may be utilized to intermittently indicate timepassage. In connection with the dial minute indicia marks 285 I providetwo concentric conductors 286 and 281 which are in opposite sides of acircuit composed of the supply conductors 288 and cutout switch 289,conductor 290 from one side of the cutout switch 289 to the conductor281, the conductor 29| from the opposite side of the cutout switch 289to one terminal point 292 of an electric bell 293, the conductors 294between the terminal point 295 and the conductor 286 and terminal switch296 and 291. At the commencement of a boxing bout, an oflicial willthrow the switch 289 to closed position and as the bout progresses theminute hand 68' revolving around the dial I4' will complete circuitthrough each of the switches 296 and 291. As the hand 68' contacts withone of the switches 296 thev bell or gong 293 will be soundeuand thenremain silent until the minute hand travels to the next succeedingswitch 291 during the passage of a 3 minute round'interval and uponcontacting with the switch 291 will complete circuit to energize thebell 293 to indicate that the round is completed and a one minute restperiod has commenced. As the minute hands contact with the nextsucceeding switch 296 the bell will again be energized to indicate thatthe rest period is over and the next round commenced. In this mannerautomatic indication is lgiven to the contestants, oicials andspectators and insures that the contestants are engaging in accurate 3minute rounds and are given accurate one minute rest periods.

Referring to Fig. 21 I disclose a means whereby an electric bell iscaused to be energized upon expiration of a predetermined length of timeduring a sport contest or the like. In this illustration the conductors34' and 35', solenoid 29', switch 33 and conductors 3| and 32' representlike elements as disclosed in Fig. 4 of the drawings. 298 is a relayswitch composed of terminal points 299, 300, 30| and 302 and'switch bar303. 304 is an electro-magnet adapted, upon energization, to move theswitch bar 303 from its position bridging the terminal points 300 and302 to a position bridging between the terminal points 299 and 30|. 305is an electric bell having terminals 306 and 301. Extending incommunication between the supply conductor 34' and the terminal point302 is a conductor 308. 309 is a conductor extending between theterminal points 302 and 30|. 3|0 is a conductor extending between theconductor 3| and the terminal point 300. 3|| is a conductor extendingbetween the terminal point 299 and the terminal 3|2 of theelectro-magnet 304. 3|3 is a conductor extending between the terminalpoint 3|2 of the electro-magnet 300 and the terminal 306 of the electricbell 305. 3M is a conductor extending between the terminal 3|5 of theelectro-magnet 304 and the terminal 301 of vthe electric bell 305. 3|6is a conductor extending between the conductor 3|4 and the conductor 32.

The dial I4 and hands 63 and 68 correspondl t-o the dial |4 and hands63' and 68 as disclosed in the preferred embodiment of my invention. 3|1is a switch which is adapted to be closed upon contact of the secondaryhand 68' therewith. 3|8, 3|9 and 320 are switches which are adapted tobe closed upon contact of the primary hand 63 therewith. 32| is aconductor extending between the conductorV 3|3 and one side of theswitch 3|1. 322 is a conductor extending from the opposite side of theswitch 3|1 and which is in communication with one side of each of theswitches 3|8, 3|9 and 320. 323 is a conductor which is connected withthe opposite side of eacn of the switches 3|8, 3|9 and 320 and whichcon- -ductor is connected to the conductor 3|.

When it is desirous of setting the primary and secondary hands 63 and 68in time operation, the switch 33' will be closed and electric currentwll'flow from the supply conductor 34', through the conductor 308,terminal pointv302, switch bar 303, terminal point 300, conductor 3|0,conductor 3|', solenoid 29', conductor 32, switch 33 and supplyconductor thus energizing the solenoid 29' and consequently throwing thetransmission mechanism, as hereinbelore referred to, into timeoperation. As the primary hand 63' contacts with one of the switches3|8, 3|9 or 320 and the secondary hand 30' simultaneously contacts withthe switch 3|1, circuit will be completed between the conductors 32| and323. As circuit is thus completed current will ow from the conductor34', through the conductor 303, terminal 302, switch bar 303, terminal300, conductor 3|0, conductor 323, through the closed switch 3|0, 3|9 or320, conductor 322, switch 3|1, conductor 32|, conductor 3|3,electro-magnet 304, conductor 3 I4,conductor3 |6,conductor 32', switch33 and conductor 35. Ascurrentfiowsthroughthe electro-magnet 304, thesame will become energized and will move the switch bar 303 intoposition to bridge between the terminal points 299 and 30|. When theswitch bar 303 is in this position current will ow from the supplyconductor 34' to the conductor 303, conductor 309, terminal point 30|,switch bar 303, terminal point 299, electro-magnet 304, conductor 3| 4,conductor 3|3, conductor 32', switch 33' and supply conductor 35', thusmaintaining the electromagnet 304 energized. As the switch bar 303 movesas just described circuit will be broken between the terminal points 302and 300 and consequently the solenoid 29' will become deenergized, thetrasmission mechanism will become inoperative and the primary andsecondary .hands 03' and 03 will remain stationary. As

current ilows through the conductor 32|, it will be circuited throughthe conductor 3|3, electric bell 300, conductor 3|4, conductor 3|6,conductor 32', switch 33' and supply conductor 35' and the electric bellwill become energized and give audible warning that a predeterminedlength oi' time has expired. When it is desirous of silencing theelectric bell 305, the switch 33 may be opened and current will be cutof! to the electro-magnet 304 and the Vswitch bar 303 will return toposition to bridge the terminal points 300 and 302 and consequentlybreak circuit between the terminal points 299 and 30| thus cutting of!current to the electric bell 300. Thetransmission mechanism may again beput into operation by closing the switch 33' and current will beconducted as hereinbetore described through the solenoid 29' which willoperate to throw the motive transmission into time operation ashereinbefore described.

The switches 3|0, 3|9 and 320 are preferably disposed at 20 minuteintervals around the dial I4', as, in professional hockey, 20 minutesdesignates the duration of each period during the contest. If desiredthe switches 3|0, 3|9 and 320 may be disposed, or a. greater pluralityof such switches may be provided to accommodate the timing of differentsport contests.

The foregoing specification and annexed drawings disclose the preferredembodiment of my invention, but it is to be understood that minorchanges may be resorted to in the commercial adaptation of my inventionwithout departing from the scope of the invention as hereinafterclaimed.

The purpose of rotating the Khands 05 and 68 at thespeed of the secondhand, is to enable the hands'to be reset in relative positions to eachotherl'at zero or any desired place on the dial at the faster speedofthe second hand. Inother words itis important under some if not mostuses of thevindicating device to reset thehands in the shortest possibletime in order that the device may be a'vailable,y!or example, betweentwo bouts of'a boxing show, or twov hockey games. The reset mechanismwhereby the second hand or hands picks up the minute hand or hands androtates both at the fast speed of the second hand, maintains the handsin fixed relation, so that when the reset is completed at zero or anyother point on the dial, the reset drive is disengaged and the handswill remain in fixed relation to each other. Thus in further operationof the indicating device, the minute and second hands will start fromexactly the same point on the dial. Without a means of bringing the twohands mechanically and exactly in fixed relation to each other to startthe timing, accuracy could not be maintained, for over a period ofrunning the hands would get out of xed relation to each other.
